(Control Method According to Present Embodiment)

First, a control method according to the present embodiment will be described. In the following description, an example will be described where a medical control apparatus according to the present embodiment performs processing associated with the control method according to the present embodiment.

[1] Processing Associated with Control Method According to Present Embodiment

As described above, in the case where an existing medical control apparatus is used, control associated with input/output of an image and control of an apparatus (an input source or an output destination) constituting the medical control system cannot be performed in one screen.

Therefore, the medical control apparatus according to the present embodiment enables control associated with input/output of an image and control of an input source or an output destination constituting the medical control system to be performed in one screen.

Here, examples of the input source according to the present embodiment can include, for example, an arbitrary apparatus which can become a signal source of an image signal, such as medical equipment having an imaging function such as an endoscope, an imaging device provided in an operating room, and an apparatus having a function of reproducing image data stored in a recording medium.

Further, examples of the output destination according to the present embodiment can include, for example, an arbitrary apparatus which can become an output destination of an image, such as a display device which can display an image and an apparatus having a function of recording an image in a recording medium.

More specifically, the medical control apparatus according to the present embodiment causes a plurality of display regions to be displayed in one screen, for example, as described in display examples of the following (1) to (3) (control processing).

Examples of the display screen according to the present embodiment in which a plurality of display regions are to be displayed can include, for example, a display screen of a display device provided at an arbitrary apparatus (or a display device connected to an arbitrary apparatus), such as a tablet type apparatus, a computer such as a personal computer (PC) and a communication apparatus such as a smartphone. Further, the display device constituting the display screen according to the present embodiment may be a device such as, for example, a touch panel, which can perform display and allows user manipulation.

The medical control apparatus according to the present embodiment causes a plurality of display regions to be displayed in one screen by, for example, causing control data including a command for causing display to be performed and display data to be transmitted to an apparatus at which the plurality of display regions are to be displayed in one screen (hereinafter, there is a case where the apparatus will be referred to as a “display target apparatus”). The medical control apparatus according to the present embodiment, for example, causes a communication unit (which will be described later) provided at the medical control apparatus according to the present embodiment or an external communication device connected to the medical control apparatus according to the present embodiment to transmit the control data.

By performing the control processing as described above, the medical control apparatus according to the present embodiment enables control associated with input/output of an image and control of an input source or an output destination constituting the medical control system to be performed in one screen.

Here, examples of the display regions to be displayed in one screen according to the present embodiment can include, for example, the following first display region, second display region and third display region.

Further, examples of the object according to the present embodiment can include an arbitrary display object which can be displayed on the display screen, such as, for example, a “thumbnail image corresponding to an image output from an input source or an image input to an output destination”, a “character string” and an “operation object such as a button and a slide bar, which can be manipulated by a user”. Specific examples of the object according to the present embodiment will be described in an example of display in the medical control system which will be described later.

Here, examples of the thumbnail image according to the present embodiment can include a still image and a moving image. Further, the thumbnail image according to the present embodiment may be regularly updated, for example, every 1 [FPS] or may be irregularly updated. By the thumbnail image being updated, an image most recently output from the input source or an image most recently input to the output destination can be reflected in the thumbnail image.

(1) First Example of Display in One Screen Through Control Processing

The medical control apparatus according to the present embodiment causes the first display region, the second display region and the third display region to be displayed in one screen.

In the case where display according to a first example is performed, the medical control apparatus according to the present embodiment causes the following objects to be respectively displayed in the first display region, the second display region and the third display region.

-   -   First display region: objects relating to the input source     -   Second display region: objects relating to the output         destination at which an image of the input source can be         displayed     -   Third display region: objects for controlling the input source

Specific examples of the display according to the first example can include, for example, a Sources screen on a device control screen which will be described later. Note that it goes without saying that the “specific examples of the display according to the first example” and “examples of objects to be respectively displayed in the first display region, the second display region and the third display region” are not limited to the above-described examples.

The medical control apparatus according to the present embodiment causes the first display region and the third display region to be displayed in one screen.

In the case where display according to the second example is performed, the medical control apparatus according to the present embodiment causes, for example, the following objects to be respectively displayed in the first display region and the third display region.

-   -   First display region: objects relating to the input source which         can cause the output destination to perform display or objects         relating to the input source which can cause the output         destination to record an image     -   Third display region: objects for controlling the output         destination

Specific examples of the display according to the second example can include, for example, a Monitors screen in the device control screen which will be described later and a Recorders screen in the device control screen which will be described later. Note that, it goes without saying that the “specific examples of the display according to the second example” and the “examples of the objects to be respectively displayed in the first display region and the third display region” are not limited to the above-described examples.

(3) Third Example of Display in One Screen Through Control Processing

The medical control apparatus according to the present embodiment causes the second display region and the third display region to be displayed in one screen.

In the case where display according to the third example is performed, the medical control apparatus according to the present embodiment causes, for example, the following objects to be respectively displayed in the second display region and the third display region.

-   -   Second display region: objects relating to the output         destination at which an image of the input source can be         displayed     -   Third display region: objects for controlling the input source.

Specific examples of the display according to the third example can include, for example, a Recorders screen in the device control screen which will be described later. Note that, it goes without saying that the “specific examples of the display according to the third example” and the “examples of the objects to be respectively displayed in the second display region and the third display region” are not limited to the above-described examples.

The medical control apparatus according to the present embodiment causes one or both of the first display region and the second display region, and the third display region to be displayed in one screen as described in, for example, the first example of the display described in the above (1) to the third example of the display described in the above (3) by performing the control processing associated with the control method according to the present embodiment.

Here, the first display region is a display region in which objects relating to the input source are to be displayed, and the second display region is a display region in which objects relating to the output destination are to be displayed. Further, the third display region is a display region in which objects for controlling the input source or the output destination are to be displayed.

Therefore, by the control processing being performed, it is possible to cause, for example, “control associated with input/output of an image signal to/from the input source or the output destination existing inside or outside an operating room and control of the input source or the output destination to be performed in one screen”. Further, as a result of the “control associated with input/output of an image signal to/from the input source or the output destination existing inside or outside an operating room and control of the input source or the output destination being able to be performed in one screen”, the user can more efficiently perform control associated with input/output an image signal to/from the input source or the output destination and control the input source or the output destination.

Therefore, by the medical control apparatus according to the present embodiment performing the control processing associated with the control method according to the present embodiment, it is possible to realize improvement of operability of the user.

Note that the above-described control processing is processing divided from the processing associated with the control method according to the present embodiment for convenience sake. Therefore, in the processing associated with the control method according to the present embodiment, the above-described control processing can be regarded as, for example, two or more types of processing (depending on an arbitrary way of dividing the processing).

(I) A device selection screen and (II) a device control screen will be described below as an example of display to be displayed on a display screen of the display target apparatus 500 in the medical control system 1000 as illustrated in FIG. 1.

(I) Device Selection Screen

FIG. 2 to FIG. 9 are explanatory diagrams for explaining an example of display in the medical control system 1000 to which the control method according to the present embodiment is applied. FIG. 2 to FIG. 9 each illustrates the whole device selection screen or part of the device selection screen to be displayed on the display screen of the display target apparatus 500. The device selection screen will be described below while referring to FIG. 2 to FIG. 9 as appropriate.

FIG. 2 illustrates an example of the device selection screen. Referring to FIG. 2, the device selection screen includes, for example, a device category selection tab (O1 illustrated in FIG. 2), a preset button (O2 illustrated in FIG. 2), a device selection button (O3 illustrated in FIG. 2), location name display (O4 illustrated in FIG. 2), an Intra-OP switch (O5 illustrated in FIG. 2), and a context menu button (O6 illustrated in FIG. 2).

The device category selection tab (O1 illustrated in FIG. 2) is a tab for switching a category of a device which can be displayed on a display screen. In FIG. 2, as the category of the device which can be displayed on the display screen, “Sources” corresponding to the input source apparatus 200, “Monitors” corresponding to the output destination apparatus 300 and “Recorders” corresponding to the apparatus 400 are illustrated. Here, FIG. 2 illustrates a case where “Sources” is selected in the device category selection tab.

The preset button (O2 illustrated in FIG. 2) is a button for making the screen transition to a screen set in advance. Here, the preset button may be highlighted, for example, by being colored, by being blinked, or the like.

The device selection button (O3 illustrated in FIG. 2) is a button for selecting a device, and by the device selection button being manipulated, the screen transitions to the device control screen which will be described later. Because, in FIG. 2, “Sources” is selected in the device category selection tab, by the device selection button being manipulated, the screen transitions to a Sources screen in the device control screen which will be described later.

Here, in the case where there are too many device selection buttons to be displayed within one screen when each of the device selection buttons is displayed at a size illustrated in FIG. 2, a scroll bar is displayed, for example, as indicated with O in FIG. 3.

Further, in the case where there are too many device selection buttons to be displayed within one screen when each of the device selection buttons is displayed at a size illustrated in FIG. 2, each of the device selection buttons may be displayed at a smaller size, for example, as illustrated in FIG. 4.

FIGS. 5A, 5B, and 5C illustrate an example of a configuration of the device selection button, and illustrates an example of the device selection button displayed in the device selection screen illustrated in FIG. 2.

The device selection button displayed in the device selection screen illustrated in FIG. 2 includes, for example, a thumbnail image (O1Z illustrated in FIG. 5A), an icon (O2A illustrated in FIG. 5A), device name display (O3A illustrated in FIG. 5A,) and status display (O4A illustrated in FIG. 5A) as illustrated in FIG. 5A.

The thumbnail image (O1Z illustrated in FIG. 5A) illustrated in FIG. 5A indicates an image output by a device which is an input source.

Here, while examples of the thumbnail image can include a still image, the thumbnail image may be a moving image. As described above, the thumbnail image according to the present embodiment can be regularly or irregularly updated. In the case where the thumbnail image is updated, it is possible to reflect an image most recently output from the input source in the thumbnail image.

Further, for example, in the case where a parameter of a device which is an input source is adjusted, or the like, in the device control screen which will be described later, the image output from the input source after the parameter is adjusted is reflected in the thumbnail image.

As an example, in the case where a parameter associated with zoom of the device which is the input source is adjusted in the device control screen which will be described later, the zoomed image is reflected in the thumbnail image.

Further, in the case where the thumbnail image cannot be acquired, display as illustrated FIG. 5B or FIG. 5C is performed in accordance with the following states.

-   -   In the case where a thumbnail has not been acquired yet: FIG. 5B     -   In the case where there is no input yet: FIG. 5C

The icon (O2A illustrated in FIG. 5A) is an icon indicating a type of the device.

The device name display (O3A in FIG. 5A) indicates name of the device. A region of the device name display (O3A in FIG. 5A) is set so as to stretch over the width of the device selection button so that, for example, long device name can be displayed.

The status display (O4A illustrated in FIG. 5A) indicates a state of the device with simple display like an icon. The status display is displayed at four comers, for example, as illustrated in FIG. 5A. Further, in the case where the status display is displayed at four comers, up to four types of status display can be displayed.

FIG. 6 illustrates another example of the configuration of the device selection button and illustrates an example of a configuration of the device selection button displayed in the device selection screen illustrated in FIG. 4.

The device selection button displayed in the device selection screen (OA) illustrated in FIG. 4 includes a thumbnail image (O1Z illustrated in FIG. 6), an icon (O2B illustrated in FIG. 6), device name display (O3A illustrated in FIG. 6) and status display (O4B illustrated in FIG. 6), for example, in a similar manner to the device selection button illustrated in FIG. 4, as illustrated in FIG. 6.

Referring to FIG. 2 again, an example of the device selection screen will be described. The location name display (O4 illustrated in FIG. 2) indicates a location such as operating room name which is currently being selected.

The Intra-OP switch (O5 illustrated in FIG. 2) is a switch for switching between a state where an operation is being performed and a state where an operation is not being performed. Here, in the case where the Intra-OP switch is put into an ON state which indicates that an operation is being performed, user manipulation set in advance and editing of various kinds of data are restricted in the device selection screen and the device control screen which will be described later.

FIGS. 7A and 7B illustrate an example of a state of the Intra-OP switch. In the case where the Intra-OP switch is put into an OFF state which does not indicate that an operation is being performed, the Intra-OP switch is, for example, put into a state as illustrated in FIG. 7A. Further, in the case where the Intra-OP switch is put into an ON state which indicates that an operation is being performed, the Intra-OP switch is, for example, put into a state as illustrated in FIG. 7B, and is more highlighted than in a case of the OFF state.

As illustrated in FIG. 7B, by highlighting the Intra-OP switch more in a case of the ON state than the Intra-OP switch in a case of the OFF state, it is, for example, possible to allow the user to recognize that the state is a state indicating that an operation is being performed.

Referring to FIG. 2 again, an example of the device selection screen will be described. The context menu button (O6 illustrated in FIG. 2) is a menu button for allowing the user to perform detailed manipulation, editing of various kinds of data, or the like.

FIG. 8 illustrates an example of the context menu displayed in the case where the context menu button is manipulated. In the case where the context menu button is manipulated, as indicated in OB in FIG. 8, context menu associated with various kinds of manipulation and editing of data is displayed.

Further, in the case where the Intra-OP switch is put into an ON state which indicates that an operation is being performed, for example, manipulation with respect to the context menu is restricted. Examples of a method for restricting manipulation with respect to the context menu can include, for example, “making items to be restricted in the context menu grayed out so that manipulation cannot be performed”, “disabling manipulation with respect to the context menu” (in this case, for example, the context menu itself is not displayed), or the like.

In the case where “Sources” is selected in the device category selection tab, the device selection screen, for example, as illustrated in FIG. 2 is displayed.

FIG. 9 illustrates another example of the device selection screen and illustrates a case where “Monitors” is selected in the device category selection tab.

Also in the case where “Monitors” is selected in the device category selection tab, the device selection screen has a configuration similar to that in the case where “Sources” is selected illustrated in FIG. 2.

Here, the device selection screen illustrated in FIG. 9 is different from the device selection screen illustrated in FIG. 2 in that “the screen transitions to a Monitors screen in the device control screen which will be described later by the device selection button being manipulated”.

Further, while not illustrated, also in the case where “Recorders” is selected in the device category selection tab, the device selection screen has a configuration similar to that in the case where “Sources” is selected illustrated in FIG. 2.

Here, the device selection screen in the case where “Recorders” is selected in the device category selection tab is different from the device selection screen illustrated in FIG. 2 in that “the screen transitions to a Recorders screen in the device control screen which will be described later by the device selection button being manipulated”.

(II) Device Control Screen

The device control screen will be described next. The device control screen corresponds to an example of a screen displayed through control processing associated with the control method according to the present embodiment. In the following description, control processing performed by the medical control apparatus 100 will be also described as appropriate.

FIG. 10 is an explanatory diagram for explaining an example of display in the medical control system 1000 to which the control method according to the present embodiment is applied and illustrates an example of a configuration of the device control screen displayed on the display screen of the display target apparatus 500.

The device control screen is configured with, for example, the following three panes (display regions).

-   -   Device pane (hereinafter, indicated with reference numeral P1)     -   Control pane (hereinafter, indicated with reference numeral P2)     -   Connect pane (hereinafter, indicated with reference numeral P3)

Here, positions where the three panes are to be displayed change in accordance with, for example, types of the device control screen (for example, a Sources screen, a Monitors screen and a Recorders screen which will be described later).

Each of the Sources screen, the Monitors screen and the Recorders screen will be described below as an example of the device control screen.

(II-1) First Example of Device Control Screen: Sources Screen

FIG. 11 to FIG. 16 are explanatory diagrams for explaining an example of display in the medical control system 1000 to which the control method according to the present embodiment is applied. FIG. 11 to FIG. 16 each illustrates the whole of the device control screen or part of the device control screen displayed on the display screen of the display target apparatus 500.

The first example of the device control screen will be described below while referring to FIG. 11 to FIG. 16 as appropriate. Here, the first example of the device control screen corresponds to a “display example in the case where the first display region, the second display region and the third display region are displayed in one screen”.

FIG. 11 illustrates an example of the Sources screen in the device control screen.

In the Sources screen illustrated in FIG. 11, for example, a button (OC illustrated in FIG. 11) for making the screen transition to the device selection screen in which “Sources” is selected in the device category selection tab is provided. The user can select another device again in the device selection screen by manipulating the above-described button (OC illustrated in FIG. 11).

Further, the Sources screen illustrated in FIG. 11 includes the Device pane P1, the Control pane P2 and the Connect pane P3 from the left side in the display screen.

In the Device pane P1 illustrated in FIG. 11, information of the device corresponding to the device selection button (O3 illustrated in FIG. 2) selected in the device selection screen in which “Sources” is selected in the device category selection tab is displayed. Here, the Device pane P1 illustrated in FIG. 11 corresponds to an example of the first display region according to the present embodiment.

FIG. 12 illustrates an example of a configuration of the Device pane P1. The Device pane P1 includes, for example, an icon (O1B illustrated in FIG. 12), device name display (O2C illustrated in FIG. 12), a thumbnail image (O3B illustrated in FIG. 12), property display (O4C illustrated in FIG. 12) and status display (O5A illustrated in FIG. 12).

The icon (O1B illustrated in FIG. 12) is an icon indicating a type of the device.

The device name display (O2C illustrated in FIG. 12) indicates name of the device. A region of the device name display (O2C illustrated in FIG. 12) is set so as to stretch over the width of the Device pane P1 so that, for example, long device name can be displayed.

The thumbnail image (O3B illustrated in FIG. 12) indicates an image output from a device which is an input source.

Here, while examples of the thumbnail image can include a still image, the thumbnail image may be a moving image. As described above, the thumbnail image according to the present embodiment can be regularly or irregularly updated. In the case where the thumbnail image is updated, it is possible to reflect an image most recently output from the input source in the thumbnail image.

Further, for example, in the case where a parameter of the device which is the input source is adjusted, or the like, in the Control pane P2 of the device control screen, an image output from the input source after the parameter is adjusted is reflected in the thumbnail image.

Further, in the case where a thumbnail image cannot be acquired, display as illustrated in FIG. 5B or FIG. 5C may be performed in the region for the thumbnail image.

The property display (O4C illustrated in FIG. 12) indicates, for example, information acquired from the device. FIG. 12 illustrates an example where model name and a manufacturer are displayed.

The status display (O5A illustrated in FIG. 12) indicates a state of the device, such as, for example, error display and an operation state.

Referring to FIG. 11 again, an example of the Sources screen in the device control screen will be described. In the Control pane P2 illustrated in FIG. 11, objects for controlling the device indicated in the Device pane P1 are displayed. Here, the Control pane P2 illustrated in FIG. 11 corresponds to an example of the third display region according to the present embodiment. Further, because the Device pane P1 corresponds to an example of the first display example according to the present embodiment, it can be said that the Control pane P2 illustrated in FIG. 11 is a display region where objects for controlling the input source apparatus 200 are to be displayed.

FIG. 13 illustrates an example of a configuration of the Control pane P2. The Control pane P2 includes, for example, a Control tab (O1C illustrated in FIG. 13) and a parameter editing region (O2D illustrated in FIG. 13).

The Control tab (O1C illustrated in FIG. 13) is a tab for each category of control. While FIG. 11 illustrates an example where one Control tab is provided in the Control pane P2, a plurality of Control tabs may be provided.

In the parameter editing region (O2 illustrated in FIG. 13), an object for manipulating the device indicated in the Device pane P1 and an object for adjusting a parameter of the device indicated in the Device pane P1 are displayed. In the parameter editing region (O2 illustrated in FIG. 13) illustrated in FIG. 13, an example is illustrated where a button for performing pan operation and tilt operation, an adjustment button and an adjustment slide bar for adjusting a zoom amount and an adjustment button and an adjustment slide bar for adjusting a focus amount are provided.

Note that, in the case where the whole objects cannot be displayed within the parameter editing region (O2 illustrated in FIG. 13), it may be possible to scroll display the objects. Further, a current zoom amount, a current focus amount, or the like, may be displayed with numerical values in the parameter editing region (O2 illustrated in FIG. 13). Further, items to be displayed in the parameter editing region (O2 illustrated in FIG. 13) can differ in accordance with a type of the device indicated in the Device pane P1.

Referring to FIG. 11 again, an example of the Sources screen in the device control screen will be described. In the Connect pane P3 illustrated in FIG. 11, objects relating to the output destination apparatus 300, at which an image output from the device indicated in the Device pane P1 can be displayed are displayed. Here, the Connect pane P3 illustrated in FIG. 11 corresponds to an example of the second display region according to the present embodiment. Further, because the Device pane P1 corresponds to an example of the first display region according to the present embodiment, it can be said that the Connect pane P3 illustrated in FIG. 11 is a display region where objects relating to the output destination apparatus 300 at which an image of the input source apparatus 200 can be displayed are to be displayed.

FIG. 14 illustrates an example of a configuration of the Connect pane P3. The Connect pane P3 includes, for example, display of a list of connection destinations (O1D illustrated in FIG. 14) and connection display (O2E illustrated in FIG. 14).

The display of a list of connection destinations (O1D illustrated in FIG. 14) indicates a list of output destination apparatuses 300 at which an image output from the device indicated in the Device pane P1 can be displayed. Examples of the output destination apparatuses 300 displayed in the display of a list of connection destinations (O1D illustrated in FIG. 14) can include, for example, the output destination apparatus 300 for which normal connection with the device indicated in the Device pane P1 is ensured upon construction (or updating) of the medical control system 1000.

Further, the display of a list of connection destinations (O1D illustrated in FIG. 14) includes, for example, a “thumbnail image corresponding to the image displayed at the output destination apparatus 300”, an “icon indicating the output destination apparatus 300” and “device name display of the output destination apparatus 300”.

Here, while examples of the thumbnail image can include a still image, the thumbnail image may be a moving image. As described above, the thumbnail image according to the present embodiment can be regularly or irregularly updated. In the case where the thumbnail image is updated, it is possible to reflect an image most recently input to the output destination apparatus 300 in the thumbnail image. Further, for example, in the case where a parameter of the input source apparatus 200 is adjusted, or the like, in the Control pane P2 of the device control screen illustrated in FIG. 13, in the thumbnail image corresponding to the output destination apparatus 300 at which an image output from the input source apparatus 200 is displayed, an image output from the input source apparatus 200 after the parameter is adjusted is reflected.

Further, in the case where the thumbnail image cannot be acquired, display as illustrated in FIG. 5B or FIG. 5C may be performed in the region for the thumbnail image.

The medical control apparatus 100 can display a thumbnail image of the image displayed on the display screen of the output destination in the Connect pane P3 corresponding to the second display region, for example, as the display of a list of connection destinations (O1D illustrated in FIG. 14) illustrated in FIG. 14.

The connection display (O2 illustrated in FIG. 14) indicates the output destination apparatus 300 selected through user manipulation with respect to the Connect pane P3.

FIG. 14 illustrates an example where the selected output destination apparatus 300 is indicated with an arrow. Note that a method for specifying the selected output destination apparatus 300 is not limited to the example illustrated in FIG. 14. Further, in the case where a plurality of output destination apparatuses 300 are selected through user manipulation with respect to the Connect pane P3, a plurality of types of connection display are displayed in the Connect pane P3.

Here, example of the user manipulation with respect to the Connect pane P3 can include, for example, the following examples. Note that, it goes without saying that the examples of the user manipulation with respect to the Connect pane P3 are not limited to the following examples.

-   -   Manipulation of touching the Connect pane P3 (in the case where         a display device of the display target apparatus 500 is a touch         panel)     -   Manipulation using a manipulation device such as a physical         button, provided at the display target apparatus 500 or an         external manipulation device such as a remote controller.

The medical control apparatus 100 causes the output destination apparatus 300 at which the image of the input source apparatus 200 is to be displayed, selected through manipulation with respect to the second display region on the basis of manipulation with respect to the Connect pane P3 corresponding to the second display region, to be specified, for example, as the connection display (O2 illustrated in FIG. 14) illustrated in FIG. 14.

Note that the Sources screen in the device control screen is not limited to the example illustrated in FIG. 11.

FIGS. 15A, 15B, and 15C illustrate an example of an image to be output from the device indicated in the Device pane P1.

There can be a case where an image to be output from the device indicated in the Device pane P1 includes, for example, an image with higher resolution than that of an image with 2K resolution or an image with high definition (HD) resolution, such as an image with 4K resolution and an image with 8K resolution.

Here, in the case where the image to be output from the device indicated in the Device pane P1 is an image with high resolution as described above, it is assumed that “a user such as a healthcare professional desires to display an image corresponding to part of the image illustrated in FIG. 15A, for example, as illustrated in FIG. 15B and FIG. 15C at a different output destination apparatus 300”.

Therefore, the Sources screen in the device control screen may be a screen which enables an image corresponding to part of the image to be displayed at a different output destination apparatus 300 on the basis of the user manipulation. By causing an image corresponding to part of the image to be displayed at a different output destination apparatus 300, for example, it is possible to “cause an image obtained by changing an angle of view of the image of one input source apparatus 200 to be displayed at a different output destination apparatus 300”.

FIG. 16 illustrates another example of the Sources screen in the device control screen.

While the configuration of the Sources screen illustrated in FIG. 16 is basically similar to the configuration of the Sources screen illustrated in FIG. 11, there is a difference in that “the output destination apparatus 300 at which an image corresponding to part of the image output from the device indicated in the Device pane P1 is to be displayed is specified”.

For example, in the case where part of the thumbnail image is selected as illustrated in O1E and O2F in FIG. 16 through user manipulation with respect to the Device pane P1 and the output destination apparatus 300 is selected through user manipulation with respect to the Connect pane P3, as illustrated in O3C and O4D in FIG. 16, the output destination apparatus 300 at which an image of the selected part of the thumbnail image is to be displayed is further specified.

Here, examples of the user manipulation with respect to the Device pane PI can include, for example, the following examples. Note that, it goes without saying that the examples of the user manipulation with respect to the Device pane P1 are not limited to the following examples.

-   -   Manipulation which can select a region on a display screen, such         as pinch manipulation with respect to a thumbnail image of the         Device pane P1 (in the case where the display device of the         display target apparatus 500 is a touch panel)     -   Manipulation using a manipulation device such as a physical         button, provided at the display target apparatus 500 or an         external manipulation device such as a remote controller

The medical control apparatus 100 may further cause the “output destination apparatus 300 at which an image corresponding to part of the image of the input source apparatus 200 selected through manipulation with respect to the Device pane P1 is to be displayed, and which is selected through manipulation with respect to the Connect pane P3, to be specified” on the basis of manipulation with respect to the Device pane P1 corresponding to the first display region and manipulation with respect to the Connect pane P3 corresponding to the second display region, for example, as 01E to 04D illustrated in FIG. 16.

(II-2) Second Example of Device Control Screen: Monitors Screen

FIGS. 17, 18A, 18B, 18C, and 18D are explanatory diagrams for explaining an example of display in the medical control system 1000 to which the control method according to the present embodiment is applied. FIGS. 17, 18A, 18B, 18C, and 18D each illustrate the whole of the device control screen or part of the device control screen displayed on the display screen of the display target apparatus 500.

A second example of the device control screen will be described below while referring to FIGS. 17, 18A, 18B, 18C, and 18D as appropriate. Here, the second example of the device control screen corresponds to a “display example in the case where the first display region and the third display region are displayed in one screen”.

FIG. 17 illustrates an example of the Monitors screen in the device control screen.

The Monitors screen illustrated in FIG. 17 includes the Connect pane P3, the Device pane P1 and the Control pane P2 from the left side of the display screen.

In the Connect pane P3 illustrated in FIG. 17, objects relating to the input source apparatus 200, which can be displayed at the output destination apparatus 300 selected in the device selection screen in which “Monitors” is selected in the device category selection tab, are displayed. Here, the Connect pane P3 illustrated in FIG. 17 corresponds to an example of the first display region according to the present embodiment.

FIG. 17 illustrates an example where a list of objects respectively relating to the input source apparatuses 200 is displayed in the Connect pane P3. Examples of the objects relating to the input source apparatuses 200 can include, for example, a thumbnail image, an icon and device name display as with the case of the display of a list of connection destinations (O1D illustrated in FIG. 14) illustrated in FIG. 14.

Further, examples of the input source apparatus 200 displayed in the Connect pane P3 can include, for example, the input source apparatus 200 for which normal connection with the device indicated in the Device pane P1 is ensured upon construction (or updating) of the medical control system 1000.

In the Device pane P1 illustrated in FIG. 17, information of the device corresponding to the device selection button selected in the device selection screen in which “Monitors” is selected in the device category selection tab is displayed. Here, the configuration of the Device pane P1 illustrated in FIG. 17 is similar to the configuration of the Device pane P1, for example, illustrated in FIG. 12.

In the Control pane P2 illustrated in FIG. 17, objects for controlling the device indicated m the Device pane P1 are displayed. Here, the Control pane P2 illustrated in FIG. 17 corresponds to an example of the third display region according to the present embodiment. Further, the device indicated in the Device pane P1 is the output destination apparatus 300 selected in the device selection screen in which “Monitors” is selected in the device category selection tab. Therefore, it can be said that the Control pane P2 illustrated in FIG. 17 is a display region where objects for controlling the output destination apparatus 300 are to be displayed.

Examples of the objects for controlling the device indicated in the Device pane P1, displayed in the Control pane P2 of the Monitors screen in the device control screen can include the following examples.

-   -   Button indicated as “Swap” in FIG. 17: a button for switching         between a main display region and a sub display region in the         case where the device indicated in the Device pane P1 has a PinP         function (function of allowing a plurality of display regions in         which images can be independently displayed to be provided in         one screen)     -   Button indicated as “Flip” in FIG. 17: a button for controlling         a direction of display in the device indicated in the Device         pane P1     -   Adjustment button indicated as “Contrast” in FIG. 17: a button         for adjusting contrast in the device indicated in the Device         pane P1     -   Adjustment button indicated as “Color” in FIG. 17: a button for         adjusting luminance, color phase or balance of RGB in the device         indicated in the Device pane P1     -   Button indicated as “2D/3D Mode” in FIG. 17: a button for         controlling switching of a display mode associated with         stereoscopic view in the device indicated in the Device pane P1

Note that the objects for controlling the device indicated in the Device pane P1, displayed in the Control pane P2 of the Monitors screen in the device control screen are not limited to the above-described examples.

For example, in the case where the device indicated in the Device pane P1 has a PinP function, in the Control pane P2 of the Monitors screen in the device control screen, an object for changing a configuration of the display region in the PinP function may be further displayed. Note that the object for changing the configuration of the display region in the PinP function can be also displayed in other panes such as the Device pane P1. In the case where the object for changing the configuration of the display region in the PinP function is displayed in a pane other than the Control pane P2 illustrated in FIG. 17, the pane in which the object for changing the configuration of the display region in the PinP function is displayed plays a role as the third display region according to the present embodiment.

Examples of the configuration of the display region in the PinP function can include, for example, examples illustrated in FIGS. 18A, 18B, 18C, and 18D. In FIGS. 18A, 18B, 18C, and 18D, the display regions indicated with “a”, “b”, “c” and “d” correspond to the display regions in the PinP function

In the case where the device indicated in the Device pane P1 corresponding to the output destination apparatus 300 has a PinP function, the medical control apparatus 100 may cause an “object for controlling display in one or more of display regions associated with PinP in the output destination apparatus 300 to be displayed in the Control pane P2 corresponding to the third display region”, for example, as the button indicated as “Swap” in FIG. 17.

Further, an object for controlling the device indicated in the Device pane P1, displayed m the Control pane P2 of the Monitors screen in the device control screen can differ in accordance with a type of the device indicated in the Device pane P1.

For example, in the case where the device indicated in the Device pane P1 does not have a PinP function, the button indicated as “Flip” in FIG. 17 does not have to be displayed.

(II-3) Third Example of Device Control Screen: Recorders Screen

FIG. 19A and FIG. 19B are explanatory diagrams for explaining an example of display m the medical control system 1000 to which the control method according to the present embodiment is applied. FIG. 19A and FIG. 19B each illustrates the whole of the device control screen displayed on the display screen of the display target apparatus 500. The screen is switched between the device control screen illustrated in FIG. 19A and the device control screen illustrated in FIG. 19B through user manipulation.

A third example of the device control screen will be described below while referring to FIG. 19A and FIG. 19B as appropriate. Here, the third example of the device control screen illustrated in FIG. 19A corresponds to the “display example in the case where the first display region and the third display region are displayed in one screen”. Further, the third example of the display control screen illustrated in FIG. 19B corresponds to the “display example in the case where the second display region and the third display region are displayed in one screen”.

FIG. 19A illustrates an example of the Recorders screen in the device control screen.

The Recorders screen illustrated in FIG. 19A includes the Connect pane P3, the Device pane P1 and the Control pane P2 from the left side of the display screen in a similar manner to the Monitors screen illustrated in FIG. 17.

In the Connect pane P3 illustrated in FIG. 19A, objects relating to the input source apparatus 200 which can output an image signal to the apparatus 400 selected in the device selection screen in which “Recorders” is selected in the device category selection tab are displayed. Here, the Connect pane P3 illustrated in FIG. 19A corresponds to an example of the first display region according to the present embodiment.

FIG. 19A illustrates an example where a list of objects each relating to the input source apparatus 200 is displayed in the Connect pane P3 as with the case of FIG. 17. Further, examples of the input source apparatus 200 displayed in the Connect pane P3 illustrated in FIG. 19A can include, for example, the input source apparatus 200 for which normal connection with the device indicated in the Device pane P1 is ensured upon construction (or updating) of the medical control system 1000.

In the Device pane P1 illustrated in FIG. 19A, information of the device corresponding to the device selection button selected in the device selection screen in which “Recorders” is selected in the device category selection tab is displayed. Here, the configuration of the Device pane P1 illustrated in FIG. 19A is similar to the configuration of the Device pane P1, for example, illustrated in FIG. 12.

In the Control pane P2 illustrated in FIG. 19A, objects for controlling the device indicated in the Device pane P1 are displayed. Here, the Control pane P2 illustrated in FIG. 19A corresponds to an example of the third display region according to the present embodiment. Further, the device indicated in the Device pane P1 is the apparatus 400 selected in the device selection screen in which “Recorders” is selected in the device category selection tab. Therefore, it can be said that the Control pane P2 illustrated in FIG. 19A is a display region where the objects for controlling the apparatus 400 are to be displayed.

Examples of the objects for controlling the device indicated in the Device pane P1, which are displayed in the Control pane P2 of the Recorders screen in the device control screen can include the following examples. Note that, it goes without saying that the examples of the objects for controlling the device indicated in the Device pane P1, which are displayed in the Control pane P2 of the Recorders screen in the device control screen are not limited to the following examples.

-   -   Recording button for starting recording of image data in a         recording medium (O1F illustrated in FIG. 19A)     -   Stop button for stopping processing being performed (O2G         illustrated in FIG. 19A)     -   Pause button for pausing processing being performed (O3D         illustrated in FIG. 19A)     -   Reproduction button for starting reproduction of image data         stored in a recording medium (O4E illustrated in FIG. 19A)     -   Rewind button for rewinding an image being reproduced (O5B         illustrated in FIG. 19A)     -   Fast-forward button for fast-forwarding an image being         reproduced (O6A illustrated in FIG. 19A)

According to the device control screen illustrated in FIG. 19A, it is, for example, possible to control recording of image data in the device indicated in the Device pane P1 from the input source apparatus 200 selected through user manipulation with respect to the Connect pane P3.

FIG. 19B illustrates another example of the Recorders screen in the device control screen.

The Recorders screen illustrated in FIG. 19B includes the Device pane P1, the Control pane P2 and the Connect pane P4 from the left side of the display screen.

The Device pane P1 illustrated in FIG. 19B and the Control pane P2 illustrated in FIG. 19B are respectively the same as the Device pane P1 illustrated in FIG. 19A and the Control pane P2 illustrated in FIG. 19A. Here, the Control pane P2 illustrated in FIG. 19B corresponds to an example of the third display region according to the present embodiment. Further, the device indicated in the Device pane P1 is the apparatus 400 selected in the device selection screen in which “Recorders” is selected in the device category selection tab. Therefore, it can be said that the Control pane P2 illustrated in FIG. 19B is a display region where the objects for controlling the apparatus 400 are to be displayed.

In the Connect pane P4 illustrated in FIG. 19B, objects relating to the output destination apparatus 300 at which an image output from the device indicated in the Device pane P1 can be displayed are displayed as with the case of the Connect pane P3 illustrated in FIG. 11 and FIG. 14. Here, the Connect pane P4 illustrated in FIG. 19B corresponds to an example of the second display region according to the present embodiment.

As described above, the Connect pane P4 illustrated in FIG. 19B corresponds to the second display region according to the present embodiment as with the case of the Connect pane P3 illustrated in FIG. 11 and FIG. 14. Therefore, the medical control apparatus 100 can cause a thumbnail image of the image displayed on the display screen of the output destination to be displayed in the Connect pane P4 corresponding to the second display region as with the case of the Connected pane P3 illustrated in FIG. 11 and FIG. 14.

According to the device control screen illustrated in FIG. 19B, it is, for example, possible to cause the image reproduced in the device indicated in the Device pane P1 to be displayed at the output destination apparatus 300 selected through user manipulation with respect to the Connect pane P4.

Here, among the apparatuses 400 selected in the device selection screen in which “Recorders” is selected in the device category selection tab, there can exist an apparatus having both an image recording function and an image reproducing function, that is, an apparatus which functions as the output destination and the input source.

In order to control the apparatus 400 which functions as the output destination and the input source as described above, one of the device control screen illustrated in FIG. 19A and the device control screen illustrated in FIG. 19B is insufficient.

Here, for example, if the Connect pane P4 illustrated in FIG. 19B is further displayed on the device control screen illustrated in FIG. 19A, it is possible to sufficiently control the apparatus 400 which functions as the output destination and the input source as described above. However, in the case where a size or resolution of the display screen is not large enough, such as in the case where the display target apparatus 500 is a tablet type apparatus, there is a possibility that visibility degrades by the Connect pane P4 illustrated in FIG. 19B being further displayed in the device control screen illustrated in FIG. 19A.

Therefore, the medical control apparatus 100 causes the screen to be switched between, for example, the device control screen illustrated in FIG. 19A and the device control screen illustrated in FIG. 19B and displayed on the basis of user manipulation.

Here, examples of the user manipulation for switching display of the device control screen can include, for example, the following examples. Note that, it goes without saying that the examples of the user manipulation for switching the display of the device control screen are not limited to the following examples.

-   -   Manipulation which can switch the display of the display screen,         such as manipulation of swiping the display screen (in the case         where the display device of the display target apparatus 500 is         a touch panel)     -   Manipulation using a manipulation device such as a physical         button provided at the display target apparatus 500 or an         external manipulation device such as a remote controller
